|     Note: A total of 1023 base address settings are available. The jumpers  |
|     are a binary representation of the decimal memory addresses. W13/A is   |
|     the Most Significant Bit and jumper W13/J is the Least Significant Bit. |
|     The jumpers have the following decimal values: W13/A=512, W13/B=256,    |
|     W13/C=128, W13/D=64, W13/E=32, W13/F=16, W13/G=8, W13/H=4, W13/I=2,     |
|     W13/J=1. Open the jumpers and add the values of the open jumpers to     |
|     obtain the correct memory address. (Open=1, Closed=0)                   |
